GRASS YIELDS

MANURIAL CONTROL. Wide variations in grass yield are disclosed in the report on the Marton top-dressing trials which appears in the November issue of the Journal of Agriculture. The report, which covers three consecutive years, shows that the daily yield of green growth on the “no manure” areas varied in one season between 6.41 b per acre per day to 1421 b. The following season’s range was from 3.91 b to 2281 b per day. Last year the range was from 11.91 b to 2081 b per acre per day. The vagaries of the season are indicated in the statements that in 1928-29 the highest yield, was recorded between December 21 and December 31, and the lowest yield between April and May. In 1929-30 the highest daily yield of green herbage took place during the first ten days in October and the lowest between February and May. Last year early December was the peak period. and May-July the lowest period as far as daily yield is concerned. “It is obvious,” states the report, “from the figures presented that super lends itself better to manipulation of applications so as to spread production more evenly over the year than slag does under conditions such as those at Marton. ’ ’
